Your actual wins minus your expected wins from all-play. If you'd beat 70% of the league in an average week but your record is .400, your schedule has been unlucky.
A grid of every team's record if it had played any other team's schedule, so you can see exactly whose opponents kept scoring big.
Private leagues work too. If you aren't the commissioner, League Lens gives you a one-tap message to send them asking to turn on 'Make League Viewable to Public' (League, Settings, Basic Settings). On a computer you can also connect your own ESPN login instead.
